I look at this is an expression of "the American way". We all know a coyote when we see one, we all know a story about a coyote when we read it. Almost all the time I use the term "coyote" when talking about the coyote, but occasionally it gets old writing coyote, coyote, coyote, coyote. For a little spice I will throw in a variation. Dog, song dog, brush wolf and many many more, all work for me, but I do prefer to use them in moderation.
On to another touchy subject brought up in this thread. For lots of you fellas taking a domestic dog is a very, even extremely difficult subject. Occasionally this love for the domesticated dog goes far beyond common sence. I do not go around killing domesticated dogs that I see in the wild, but I have put down the occasional dog. This standard has changed with the locall that I live in. In upsate New York Fish & Game pushed this practice as almost your god required duty. Basicly, you see a dog unaccompanied in the woods you were to kill it. I would not do this unless I actually saw them in hot pursuit of a deer. Out west (where the bulk of this arguement seems to be strongest) I mostly leave them alone. That is unless a rancher is having problems with particular dogs. It that case I try to get a rock solid description of the problem dog/dogs. I will generaly take these dogs if they are called. I have also called abandoned dogs near indian reservations, sometimes these diseased wrecks of once beautiful dogs are seriously in need of killin' (we are talking about limping, open sores, skin and bone creatures that have little chance of making it) and have taken a few of those.
